iOS4 addPerson stack overflow

[watkyn]

I am having an issue trying to run the sample application with the latest iphone 4 SKD. When I try to add a new person I get a “EXC_BAD_ACCESS” and the backtrace looks to be a recursive issue in the NSObject+XMLSerializationSupport (toXMLElementAs:)

I first noticed this in one of my apps, but since I was able to reproduce it in the demo app, I figured I would point it out.

Works fine in the 3.2 simulator but crashes in the 4.0 simulator and device.

I had the same issue, but worked out what was happening.

The properties of the object has a range of extra elements in 4.0. Some of which are of types that can't be serialised.

A work around I found was to explicitly exclude these properties from serialisation.

Inside NSObject+ObjectiveResource.m change the defaultExclusions inside convertToRemoteExpectedType:

NSArray *defaultExclusions = [NSArray arrayWithObjects:[self getRemoteClassIdName],@"createdAt",@"updatedAt",@"accessibilityFrame", @"accessibilityHint", @"accessibilityLabel", @"accessibilityLanguage", @"accessibilityTraits", @"accessibilityValue", @"isAccessibilityElement",nil];

If someone else can comment on a better solution, that would be great.
